How is blood type determined?
Sweating and goosebumps
These two divisions in the nervous system control the body during times of stress and during times of relaxation.
Resting Sarcomere-> Active Site Exposure ->Cross Bridge Formation-> Myosin Reactivation -> Cross Bridge Detachment-> Pivoting of myosin head.
What are the steps of muscle contraction?
Superior and Inferior Vena Cava->Right Atrium->Tricuspid Valve->Right Ventricle ->Pulmonary Semilunar Valve->Pulmonary Arteries->Pulmonary Circulation ->Pulmonary Veins->Left Atrium->Bicuspid Valve->Lt Ventricle->Aortic Semilunar Valve->Ascending Aorta->Aortic Arch->Descending Aorta
